1, commonly used computers, stealing vitamin a.
People who often face computers and TV screens often have to bear the change and flicker of light intensity, which will consume a lot of vitamin A, which can constitute the photosensitive substance on the surface of retina.
Coping method: increase the supply of vitamin A in the diet. We can choose foods rich in vitamin A, such as animal liver, egg yolk, cheese, whole milk, high-fat marine fish, and we can also supplement various orange vegetables and fruits, such as carrots, pumpkins, papaya, and various green leafy vegetables, such as spinach, kale and oil cabbage. Because the carotene they contain can be converted into vitamin A in the body.
2. Drink too much and steal B vitamins.
Drinking a lot will consume the water-soluble vitamins stored in the body, especially the B vitamins, because alcohol metabolism will be consumed. Therefore, people who often drink a lot should take more B vitamins to avoid emotional instability and listlessness caused by lack.
Coping methods: coarse grains such as oats, millet and red beans, lean meat and peanuts are all rich in B vitamins. Need to be reminded that B vitamins are easy to be lost in alkaline environment, so do not add alkali when cooking miscellaneous grains porridge.
3, old smoking, stealing vitamin C.
Auspicious ingredients such as tar in cigarettes will consume a lot of vitamin C. According to statistics, smoking a cigarette consumes about 25 mg of vitamin C; If it is passive smoking, the loss of vitamin C is even greater, up to 50 mg.
Coping methods: Therefore, people who have smoking habits or often passively inhale second-hand smoke should usually eat more foods rich in vitamin C, mainly vegetables and fruits, such as fresh dates, kiwis and oranges, green peppers and mustard greens.
4. Drink strong tea and steal iron.
Many people like strong tea, but tea contains glume, which reacts with iron in food to produce new substances that are difficult to dissolve, which will hinder the absorption of iron, especially for people with iron deficiency anemia.
Coping method: It is suggested that health tea should be light and moderate. Also, pay attention to eating foods rich in iron, such as lean meat, animal liver, eggs, animal whole blood (duck blood, pig blood) and so on.
5. Eat too salty and steal calcium.
The study found that the more salt intake, the more calcium excreted in urine, and the worse calcium absorption.
Coping methods: In addition to learning to calculate the salt in salt cans, we should also pay attention to foods containing a lot of "invisible salt", such as sausages, meat, canned food, instant noodles and other processed foods. People with heavy tastes should eat more foods with high calcium content such as green leafy vegetables, dairy products and bean products, and at the same time reduce the intake of salt appropriately.
6, calcium and phosphorus imbalance, drive away calcium.
The imbalance between calcium and phosphorus is the chief culprit leading to calcium deficiency. Under normal circumstances, the ratio of calcium and phosphorus in human body is 2: 1. But in real life, people eat too much phosphorus-containing food, and the phosphorus intake often exceeds 10 times.
Coping methods: carbonated drinks, cola, coffee, hamburgers, pizza, wheat germ animal liver, French fries and other foods containing a lot of phosphorus should be eaten as little as possible.
